4 Claims.

, The present invention relates to tap bush and method of making the same.

Recently, metal barrels and kegs have been employed by manufacturers of liquors for packaging the liquors. The use of metal barrels for such purposes has created a demand for tap bushes which may be welded or screwed in place in the barrels and which must be made at minimum cost to the barrel manufacturers, and which, at the same time, must be capable of receiving the taps in'use at the present time.

i Thepresent invention, therefore, is addressed to such tap bushes and is concerned with tap bushes which are Ymade in two separate parts, and subsequently fastened together in permanent relation.

The body member of the bush of the present invention, which is the part of the bush secured to thebarrel, is fashioned from a blankby tool action, that is to say, the body may be formed by stamping, spinning, or drop or press forging. The neck member may be forged, stamped or c ast.

In order that a tap may be applied to a bush of the present invention, in the usual manner, the

, body and neck members of the bush must be prevented from relative rotation during the application of the tap.

An object of the present invention is to provide tap bushes which are readily applicable to metal barrels.

Another object of the invention is to provide a method 'of making tap bushes by tool action.

A further object of the invention is to provide a method of making tap bushes whereby eilcient and-satisfactorybu-shes may be madeat minimum cost andwhich bushes are easily secured in place in metal barrels. A still further object of the invention is to provide forged tap bushes for metal barrels. Generally speaking, the tap bush ofthe present invention ispmade in two parts, one the body part or member and the other the neck part or member. The body member is formed by tool action, such as spinning, stamping or forging, while the neck may be forged r cast. The two membersV are then assembled togetherin permanent association in such Amanneras to prevent relative rotation between these members,

The method of the present invention contemassembling 4these parts together in permanent relationship. A

,n The above, other and lfurther objects of the inventionwill be apparent from the following def relationship prior to permanent connection.

The drawings will now be explained.

The tap bush of the present invention comprises a body member A and a neck member B.

The body member A is formed from a vblank 0r piece of metal by tool action, such as by stamping,

spinningV or forging into the intendedbody' form',

as illustrated in Figure 2. l

` The body member A, as illustrated in Figure 2,

is fashioned to provide an upper marginal ati-iii taching flange I, a central upstanding collar 2.

for receiving the pumprod, or a cork, and the collar is connected' at the inner end ofthe loush-V i ing to a flange which defines the inner face-'ofthe bushing and connects the collar with'the outer of the body A, the lower portion thereof'is'i'ni clined, preferably, `as 'illustrated at 3, torigidify the body member and at `the same time tc-.profV vide a pocket for welding material 'when' Y the bush is secured in a Ametal barrel. The body A of Figurezis shown as provided with indenta tiens 4, which are formed bybeing inwardlyA struck from the exterior fthebody member adjacent the collar 2to provide lugs on the in.

terior of the body for cooperating with'theneck member Bjto prevent relative rotation between the neckmember and thebody.member.Y

The neck memberB, as'illustrated in elevation in Figure', includes abodyportion 5 a'bottom outturned flange 6 which is provided with aper' tures I to receive the lugs 4 of the bodymem? 'I,' the lower surface of which is inclinedat 8 downwardly from the4 entering end 9. Atthe end of the inclined po'rtion'S the neck is formed with .ai st'ov'r'JvIIl,Y against which the lugs IIjon. the tapv abut, when the tap is properly attached to Ithev bush. There are two such flanges ,'I .with jthe Y recesses l2Y therein formed `by the termination of the ends 9 of the tapered part Band spaced from 4the adjacent lug I0, as illustratedin the'draw-V ings andas well understood in the ,art.-

VThe neckB has, preferably, the upper portion of its hollow interior flared outwardly at its upper end, as illustrated `at I 3, to receive the upper end ofthe collar 2 of the body member,

whenjthe same is flared by suitable tool'action to permanently connect Vtogether the neck and thebody.V Y A Afterthe neck B and body A have beenassembled, as illustrated in Figure 2; the assembled bush structed in the manner described.

isthen subjected 'to suitable tool actionto :flare the end of the collar2riso as to overlie theupper end of the neckB, as villustrated in Figure` 3. This aring- Vof .the upper. end of the` collar ,2

Y permanently connects together the neck and thel If desired,..the flared extremity .of thecollar 2 may-be welded totheneck B. Y Y Y. Intheform of bush illustrated Vin Figures 5 and 6, thebody member A is mader as aforg-ing. The body member A' is submitted to suitabletool action, such as a forgingn machine, to provide the collar I4 fortreceiving the purnprod; i

dif member' A., there In the formation f the bf The forged'bush', vjust described, maybe se-V are fashioned two inwardly projecting lugs I5, which have their extremities recessed as at I6. In the formation of the neck'B' the projections I'I are formed thereon which are shaped to engageV the recesses I6 of the lugs I5 and thus interlock 5y the neck and body members to prevent relative rotation between these members. In this form offfthe inventiomthe neck andV body arefsecured together in vpermanent relationship by flaringthe upper endof the collar- Ill to overlie the upper endof the neck B. This flaring is accomplished by spinningy or by other suitable means,-and when so'ared the extremity of the collar may be weldedttof the neck B'.

curedinuposition in a metal barrel by welding, or, if desired, 4 itmay be threaded to engage neck isprov'idedwith'the flanges 20 separated by l lug receivingapertures, not shown, and'pro` vided with stops 2|, adjacent these apertures or "30 slotsito yserve as limits Afor theV` rotation of the tap whenapplied to the bush.` -In thisV form of`4 theinvention the uppery end of the collar I8 is" flared over theneck B2 when it is applied to theY annular groove I9,4 thus Vsecuring together in- 35 permanent. relationship the neck andbody "members.v If desired, the joint so" made may be Ywelded..

In the forms of theLinvention sc ufardescribed,v the Y.necksv have been secured Vto the bodies byV flaringjthe upper ends of the rod receiving collars of the bodymembers.Y

:In the form er the invention iuustrated in FigT ures '11 i;' 12` andv 13,'the necks are'secured to the bottom ofthe body members by flaring the lower' outside of the bottoms of the bodymembeis.

Figure v12'illu strate's'a'bush body A3, which may be made as a forgin'afand' which, when formed; is provided with a central aperture 2l and inwardly'thereof, thebottomfof the body 'member is provided withan annular rabbet or groove 22. The neck member B3v may be formed asa forging,- vand as so" formed is provided Ywith'a finished upper extremity 23 and a hollow interior 24 serving jas the pump 7rod receiving space. The neck B3 is provided with a flange 25 whichseats in the groove or undercut 22,-in the bottom of the bodyfAlf When` the neck is fastened, it is provided'vwith'an extremity 26, which passes through'otheopening 2I in the bottom of thejbody member A3 and-is'then spun or peened, asnat 2'Ito permanently connect'the neck V and the body Y in assembledrelationship. j .l L A 'Il'ieboclyA3 is, when formed, 'provided with 65 lugs 28 havingrecessed ends 29 while theVv neck B3 is lproyidedvvith projections 30 toV enter the recesses 29 ofthe lugs 28, fork preventing relativev rotation between the n eck'andY body. .Y 1 .'Ihe'bush illustrated in Figure 13 is made'simi 70 larlyrtothat illustrated in Figure 12,v except that the body A4 is thinner than the body A3, andmayj be formedas a stamping. Y f ,Ihe bottom of the v.body A4 is provided witha centrally 'disp'csed aperture vTheV neck YB3 fis 7.5V

45- extremities ofthenecks to engage' against the,

fashioned with the rod receiving recess or opening 32, the marginal flanges 33 for cooperating with the top, and with the upper margin nished as at 34. The neck has its lower end reduced in outer diameter to provide a portion for passing through the aperture 3l in the bottom of the body A4 where the extremities of the reduced portion are then spun or peened over at to permanently connect together the neck and the body.

Figure 8 illustrates a bush of the present invention as employed in a bush opening in a metal barrel. Here the barrel is illustrated as a double walled barrel, 36 being the outer wall and 3l the inner wall.- A bush opening is provided in these walls and the bush E applied thereto and secured by welding at the joints indicated at 33.

A tap C, of well-known construction, is remov- Y ably attached to the bush by engagement of the lugs Il of the tap collar 39 passed through the notches formed in the anges of the neck, and the collar is then given rotative movement until the lugs Il engage against the stops provided in the bush. The lugs I l engage the tapered undersurfaces of the flanges to draw down the tap into tight engagement'with the neck so that the sealing washer 40 is firmly clamped between the top and the bush to provide a leak-tight joint for the pump. The pump rod 4I is then inserted through the tap C and through the recess or opening provided in the bush so that the rod may withdraw the contents of the barrel in the usual manner.

The collar 40 is tightened on the tap C by a threaded sleeve 42 cooperatively engaging the tap and the collar 40, in the usual manner.

The neck of the present invention is adapted to receive taps in use at the present time, so that it will be unnecessary to secure additional taps.

YThe body and neck are assembled, and then a part of one is wedged or otherwise forced, by suitable action, into tight engagement with the other, to connect them together in permanent relation.

In order to provide means for preventing accldental displacement of a cork in a tap, projections or lugs 43 may be suitably fashioned on the tap bush. Other similar means may be provided such, for instance, as the indentations 44 formed in the stamped bush bodyA from inside the body. The inner ends of the inserted corks swell beyond the inner ends of the cork receiving portions of the bushes, and might readily be accidentally discharged by gas pressure in the barrel unless positively secured in place. The provision of the lugs 43 and indentations 44 serve as such means.

The lugs 43 and indentations 44 may be sharpened to facilitate locking engagement with a cork.

The invention has herein been described more or less precisely, but it is to be understood that the invention is not to be limited thereby, as changes may be made in the arrangement and proportion of parts, and equivalents may be substituted, without departing from the spirit and scope of the invention.

The invention is claimed as follows:

l. A tap bush having a cork receiving opening and having integrally formed means projecting from the inner face of said bush adjacent said opening and elsewhere than within said opening for preventing accidental displacement of a cork through the outer end of said opening and being so positioned as to oler no obstruction to the passage of a pump rod through the opening.

2. A tap bush including means defining an elongated central collar integral with an outwardly extending ange which denes the inner face of said bush, said central collar bounding a bore to receive a cork, and means on said bush and integral therewith and adjacent the inner face thereof adapted to lockingly engage a cork entered in said bore against accidental movement of the cork only in an outward direction and being so positioned as to offer no obstruction to the passage of a pump rod through the bore.-

3. A tap bush including means defining an elongated central collar integral with an outwardly extending ilange which denes the inner face of said bush, said central collar bounding a bore to receive a cork, and means on said bush and integral therewith and adjacent the inner face thereof to guide the cork in its inward movement in said bore and to lockingly engage said cork against outward movement when in its normal position in the bore and being so positioned as to offer no obstruction to the passage of a pump rod through the bore.

4. A tap bush including ange means defining the inner face of the bush and provided with an opening to receive a cork, and means on said bush and integral therewith positioned adjacent said inner face to engage a side of the cork to obstruct only outward movement of the cork while orering substantially no resistance to inward movement of the cork and being so positioned as to oler no obstruction to the passage of a pump rod through the opening.
